Heathrow Airport’s chief executive has said disabled passengers who are left stranded on planes will not get compensation, after BBC journalist Frank Gardner complained of being stuck after staff misplaced his wheelchair.CEO John Holland-Kaye said: “I don’t think it’s reasonable that we should take financial responsibility,” and set a 20-minute target in which disabled passengers should be helped off the plane after landing.He told BBC Five Live disabled passengers should be able to leave the plane “20 minutes after everybody else has got off.”Mr Gardner said he was left waiting for 100 minutes because his wheelchair had been misplaced by ground staff, and claimed Heathrow would not act to change its treatment of disabled people without a financial penalty.The chief executive said in this case, the wheelchair had been mislabeled, and that was why it was taken to the correct place. The BBC’s security correspondent lost the use of his legs in 2004 after being shot six times by militants while reporting in Saudi Arabia.On Saturday morning, when he landed at the London airport, his wheelchair was mistakenly taken to the terminal instead of to the plane door.
